& what about that absolutely horrible film Life Is Beautiful which won an Oscar for taking the piss out of Auschwitz,

You seems to be itching on this one MtheGM. I'm assuming you haven't seen the film otherwise you'd realise the last thing Life is Beautiful does is to take the piss out of The Holocaust; rather it tells a deeply affecting, and harrowing story set during The Holocaust. Personally I found it preferable to Schindler's List (as far as cinematographic entertainment goes) in attempting to tackle what remains now, and perhaps eternally, unsayable.
